Effects of exchange rate changes on aggregate output in the developing counries: An applicatian for Turkey

In the developing countries, devaluations are used as an political instrument by the governments against balance of payment problems. In accordance with the literature, depreciation of the exchange rate positively affects the economy. However, exchange rate depreciation not only induces the export increase due to decreasing the prices of domestic goods but also increases the cost of producing in the export sector by increasing the input prices of imported goods. In this context, theoretic discussions about contractionary devaluation hypothesis major on supply and demand side channels.In this study, channels that introduce the basic hypothesis of new structuralist school which is the contractionary effects of exchange rate changes in the developing countries, are analyzed. In the empirical part, the effects of reel and nominal exchange rate changes on macroeconomic variables are tested based on the period which TL convertibility is accepted in 1990. It is done following by Kamin and Rogers (2000) model. Especially, exchange rate depreciation effects on GDP, domestic prices level, government size, capital account, foreign interest rates and oil prices are examined.According to the results, effects of shocks given to exchange rates both in the long run and short run are negative on reel GDP. In the other words, contrary to traditional approach, results are supporting the arguments of new structuralist school. Finally, depreciation of exchange rate contracts the aggregate output.
